Mehki feromagnetizem visokoentropijske spojine FeCoNiPdCu
Darja Gačnik, Janez Dolinšek
Magistrsko delo
Oznake: fizika trdne snovi;visokoentropijske spojine;mehki feromagneti;nanokompoziti;magnetne lastnosti;
V magistrskem delu obravnavamo magnetizem visokoentropijske zlitine FeCoNiPdCu. Najprej so opisane splošne značilnosti visokoentropijskih zlitin, nato pa še nekateri pomembni magnetni pojavi in koncepti ter kratek opis vpliva električne upornosti na delovanje magnetov v magnetnih aplikacijah. Sledi ...

Physical properties of tin-containing high-entropy alloys
Darja Gačnik, Janez Dolinšek
Doktorska disertacija
Oznake: tin;high-entropy alloys;multicomponent alloys;disordered systems;superconductivity;
The concept of introducing a maximum amount of disorder, i.e., entropy, is realized in high-entropy alloys. At first, first generation high-entropy alloys were generated as single-phase solid solutions, but nowadays, the research has shifted towards second generation high-entropy alloys, i.e., non-e ...

ǂThe ǂeffect of scandium on the structure, microstructure and superconductivity of equimolar Sc-Hf-Nb-Ta-Ti-Zr refractory high-entropy alloys
Mitja Krnel, Andreja Jelen, Stanislav Vrtnik, Jože Luzar, Darja Gačnik, Primož Koželj, Magdalena Wencka, Anton Meden, Qiang Hu, Sheng Guo, Janez Dolinšek
Izvirni znanstveni članek
Oznake: high-entropy alloys;structure and microstructure;superconductivity;
In this study, we investigate the scandium-containing Sc-Hf-Nb-Ta-Ti-Zr system of refractory high-entropy alloys (HEAs). Using the arc-melting method, we synthesized nine equimolar alloys (five 4-, three 5- and one 6-component), with all of them containing Sc. The alloys were characterized by XRD, e ...
